fix(lint): resolve all 49 lint warnings and errors across codebase

- Remove unused imports/variables in seed scripts and test files
- Replace console.log with console.warn in seed/utility scripts
- Replace `as any` with proper Prisma types (InputJsonValue, PaymentStatus, Plan, UserWhereInput)
- Fix import-x/no-named-as-default-member warnings in logger, mapbox, eslint config
- Prefix unused callback params with underscore in e2e tests
